@gskger I tried wget http://xoa.io:8888/ and it failed.

I changed the Internet firewall to allow outbound port 8888 to any any address from the server.

Now Success!

Thank you very much.

@mstollenwerk How do you mark Solved?

@heman Using SSH, the server pings google.com and my PC FQDN. From my PC, nslookup server hostname and nslookup server IP give the correct info. What other test should I do?

@gskger I'm on the same network switch and there isn't a firewall between the server and PC.

Yes, I've tried https://xen-orchestra.com/#!/xoa but I get a red message box with INTERNAL ERROR.
What log would give more info?

After installing XCP-NG 8.2 on a Supermicro X9DAi MotherBoard, (2) 2.00 gigahertz Intel Xeon E5-2620, 32 GB RAM, & (4) 1TB SSD drives in RAID 10, then I tried to set up Quick Deploy on a Windows 10 PC. After selecting the Deploy button, I got the following Pop-up Error:

{
  "code": 1,
  "message": "INTERNAL_ERROR",
  "data": [
    "Unix.Unix_error(Unix.ECONNREFUSED, \"connect\", \"\")"
  ]
}

I tried different PC's

What does the error mean and what steps should I take to solve this problem?
